android - Jumping to the top of the page with Gridview -


i using framelayout inside scrollview. on runtime, inserting framelayout fragment, it's layout gridview inside swiperefreshlayout.

the nested scrolling working good, problem when im trying on scrollview 1 of followings :

fullscroll(scrollview.focus_up)or smoothscrollto(0,0) or scrollto(0,0)

nothing happends, , gridview not top of page. (by way, getting scrollview using findviewbyid)

here code:

in main_theme.xml layout:

<scrollview     xmlns:android="http://schemas.android.com/apk/res/android"     android:id="@+id/main_theme_scroll_view"     android:layout_width="match_parent"     android:layout_height="wrap_content"     android:fillviewport="true"     app:layout_behavior="@string/appbar_scrolling_view_behavior"     android:orientation="vertical">      <framelayout android:name="com.example.ohad.myapplication.homeactivity"         android:layout_margintop="?android:attr/actionbarsize"         android:id="@+id/fragment_container"         android:layout_width="match_parent"         android:layout_height="wrap_content"/>  </scrollview>

and in home_page.xml layout (the layout of fragment load framelayout):

<android.support.v4.widget.swiperefreshlayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" android:id="@+id/home_swipe_refresh_layout" android:layout_width="match_parent" app:layout_behavior="@string/appbar_scrolling_view_behavior" android:layout_height="match_parent">      <gridview         android:id="@+id/homepage_gv"         android:layout_width="fill_parent"         android:layout_height="fill_parent"         android:background="@color/darkgray"         android:gravity="center"         android:horizontalspacing="0dp"         android:numcolumns="1"         android:nestedscrollingenabled="true"         android:paddingleft="0dp"         android:paddingtop="0dp"         android:verticalspacing="1dp" /></android.support.v4.widget.swiperefreshlayout>

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer
